As David O’Brien of the Atlanta Journal-Constitution reports, Braves left-hander Jonny Venters, who has spent the entire season rehabbing from his second Tommy John surgery, has received the devastating news that he has re-torn his left ulnar collateral ligament and will require a third Tommy John surgery if he is to continue his career. Venters says that he will address reporters Friday to further comment on the unfortunate news. O’Brien lists Jose Rijo and Jason Isringhausen as a rare pair of examples of success following a third Tommy John operation.

The Mets worked out Cuban third baseman Pavel Quesada and shortstop Roberto Carlos, reports Mike Puma of the New York Daily News (Twitterlinks). Quesada, said to be a third baseman with some pop, was the more impressive of the two, according to Puma’s sources. The 28-year-old Carlos, on the other hand, was described as a “work in progress” that needs to improve the strength of his throwing arm.

Although the Marlins are hanging on in the playoff race — they’re five and a half games out of a Wild Card spot — president of baseball operations Michael Hill tells MLB.com’s Joe Frisaro that a last-minute trade is unlikely. However, that doesn’t mean that the team will be going young in the month of September. With a postseason berth still a possibility, Hill notes that the team is less inclined to go with young players in order to give them experience when a veteran could give them a better chance at winning in a given situation. For this reason, top prospect Andrew Heaney may not get a September callup, Frisaro notes.

“He looked like a totally different guy than in Spring Training,” an American League scout told Matt Gelb of the Philadelphia Inquirer when discussing Phillies right-hander Miguel Alfredo Gonzalez. A National League scout told Gelb, “He’s a solid setup guy for me.” The Phillies are very pleased with the progress they’ve seen since Gonzalez’s injuries in Spring Training made the team’s $12MM investment look questionable. Gonzalez, who is likely to receive a September callup, has a 2.36 ERA in 34 innings since shifting to a relief role and has risen to Triple-A Lehigh Valley. He’s flashed a 95 to 98 mph fastball and could factor into the bullpen as a setup man coming out of Spring Training next year.

The Mets have long been on the lookout for a shortstop, but while many have speculated on the possibility of a trade with the Cubs or D’Backs, Mike Puma of the New York Post reports that the team will take a look at an under-the-radar Cuban shortstop in the coming days. Roberto Carlos, a 28-year-old Cuban defector, is in the Dominican Republic and garnering attention from the Mets. Carlos left the Cuban National team in 2012 and defected to America, but he is believed to have “slipped through the cracks” because he did not initially seek representation after defecting. The switch-hitting Perez last batted .339 with four homers for the Cuban National team in 2012, Puma writes, and he did have a brief stint in independent ball last season. Carlos, who until recently played under his full name of Roberto Carlos Ramirez, batted .357/.394/.425 in 293 plate appearances between two indy league clubs. He didn’t homer, but he did go 19-for-24 in stolen base attempts.

Also from Puma’s piece, while the Mets weren’t involved in the Rusney Castillo sweepstakes, the money required to sign him wasn’t the reason, according to GM Sandy Alderson. “I think it’s a matter of there might be some scouting differences of opinion, and kind of where we are and what we’re going to do in the immediate future, so there are lots of issues involved,” said the Mets GM. “We scout [the Cuban market], so it’s not as if we’re not aware of what is going on. It’s not like we’re not aware of who is out there.”

Puma also tweets that the Mets will work out Pavel Quesada as well, a Cuban third baseman who is said to possess some power. MLB.com’s Jesse Sanchez tweeted last month that Quesada worked out for several teams at the Yankees’ facility in the Dominican Republic.

Zack Wheelerspoke with Kristie Ackert of the New York Daily News and said that while he’s aware that the Mets have a perceived starting pitching surplus, he’s hoping to remain with the club rather than end up elsewhere via trade. “I’d like to be here,” said Wheeler. “I know they could use one of (the young pitchers) to get a bat or two, but I’ve been here for the rebuilding. I know it’s part of the game, but I want to be here after the rebuilding. I want to see the results.”

In an appearance with Chris Russo on the MLB Network (video link), Peter Gammons revealed that the Mets at one point last offseason offered Jon Niese to the Mariners in a trade that would have sent shortstop Brad Miller back to New York (it’s unclear what other pieces were in the deal). The Mets may be happy to have held onto Niese, who has posted a 3.50 ERA in 141 1/3 innings while Miller has struggled to a .199/.273/.326 batting line.

Gammons also opines that the Mets and Cubs don’t line up well for a trade because the Mets would likely have to part with at least two young pitchers to make a deal, and that would thin out their depth considerably.
